What are the two radii shown as'a' and 'b' in the figure known as?

A

a=atomic radius,b=molecular radius

B

a=Covalent radius,b=van der waals' radius

C

a=Ionic radius,b=Covalent radius

D

a=Covalent radius,b=Atomic radius

Text Solution

Verified by Experts

The correct Answer is:
B
a'Represents covalent radius which is the distance between the nuclei of two bonded atoms 'b' represents van der waals'radius which is the distance between nuclei of two closest molecules.
